So my partner and I have been invited to Christmas dinner at my in-laws. I had bought a bottle of champagne to take and my partner felt we ought to get something else and so chose some chocolates but then handed them to me to pay. We are both on a pension and similar income. Together over 10 years but don't live together and seperate accounts etc. I am male partner female. When I suggested she might want to pay for the chocolates she refused and said so I said so I am paying for both? She said yes as they (hosts) are my family not hers and I was nit picking. I said she was 'out of order' but this left me feeling upset and I told her and we had a row.
